A unique approach to monitoring for improved reliability

Windrock specializes in digitally transforming the way companies monitor, manage, and optimize their reciprocating machinery. Machinery such as reciprocating compressors and diesel engines require a unique approach to monitoring for improved reliability and performance due to the nature of how these machines operate. Traditional methods of vibration analysis are widely utilized on rotating machinery in all types of industrial applications to diagnose and troubleshoot machinery issues. In conjunction with other technologies, vibration analysis allows predictive maintenance personnel to pinpoint machinery failures early and take corrective action to avoid failures and save money. This technology, however, is not suited to reciprocating machinery.

Windrock offers a distinctive solution in the field

The expected mechanical events and the failure modes in reciprocating machines are best identified in a time-based waveform and referenced to a known point on each cylinder such as Top Dead Center (TDC). This crank angle-based data examines events relative to crankshaft positions. By combining vibration, ultrasound, and temperature measurements with in-cylinder pressure data and utilizing basic thermodynamic and combustion principles, it is possible to determine defects in reciprocating machine equipment. Faults such as compressor cross head damage and cylinder leakage (valves, rings, and packing) as well as engine valve train and cylinder-related issues can all be accurately identified and evaluated.

The technologies developed by Windrock include the Model 6400 portable analyzer-based systems, the Spotlight continuous monitoring systems using IIoT devices and analytics, and the state-of-the-art Platinum monitoring and protection system. Along with these solutions, Windrock provides world class services and training to support clients’ success.

PDM Technologies is committed to providing the best solutions to help companies monitor, manage, and optimize their reciprocating machinery.
